T321H High Performance Antiwear Additive For Lubricants Sulfurized Isobutylene SIB High Pressure Method
T321H Sulfurized Isobutylene (High-pressure Synthesis)
Product Overview
This additive is synthesized via a high-pressure reaction process, presenting as a pale yellow transparent liquid. It serves as a key sulfur-based component in gear oil formulations.
Key Characteristics
-
- Outstanding extreme pressure performance with strong anti-welding properties, preventing tooth surface damage under high-impact loads.
- Under high friction temperatures, its decomposition products react with metal surfaces to form a protective chemical film, reducing wear and scuffing risks.
- Exhibits superior solubility in both mineral and synthetic base oils, maintaining stability without precipitation during prolonged storage.
Applications & Dosage
Widely used in the formulation of various gear oils, metalworking fluids, and other lubricants.
Recommended dosage: 1.5–5.0%
